What is the coldest planet in the solar system? A challenging question to ask your kids when it comes to the solar system planets and their facts. Will they give you the right answer?

There are nine planets in the solar system and this is sometimes the only piece of information known by the kids and knowing their placement around the sun is another thing they might be well aware of, but not all of them know which is the biggest planet (https://www.youtube.com/watch?v=9h7DLa7o2Lc) and which is the smallest (https://www.youtube.com/watch?v=7E7zoFBwLU0) or such kind of information.

Knowing more about the solar system and its planets is one beneficial step to take while educating and homeschooling your kids, it could happen through telling them stories, reading them these stories or else giving them the permission to watch some educational videos that will provide them with the kind of information you want them to know about (https://www.youtube.com/watch?v=FTQKy19e2OQ).

Which planet in the solar system is considered the coldest? This is considered a tricky question because there are two different planets which kids usually give as answers for this question, Neptune and Uranus.

Technically speaking, Neptune is the coldest planet in the solar system but Neptune along with its neighbor planet which is Uranus are usually referred to as the "Ice giants". Both Neptune and Uranus consist of huge amounts of rock and water, ammonia, methane and ice crystals.

The average temperature on Neptune planet is -350 degree Fahrenheit and the average temperature on Uranus is -325 degrees even though Uranus is usually slightly warmer than Neptune, it does reach the coldest temperatures of any other planet; the coldest temperature ever recorded on Uranus planet was -371 degrees Fahrenheit.

While sitting in the coldest city on your planet, you will think that it could never come any colder than that, but actually it could, only if you decided to take a spaceship and go to Neptune or Uranus to experience what cold weather truly means. Actually Earth is one of the warmest planets due to its location around the sun and this is considered a good thing because humans will not be able to survive such cold weathers as the one of Neptune and Uranus.

Until today, scientists are not yet sure why these two solar system planets are the coldest, but what we have here is that they are. Solar system facts for kids should be always easy to handle and easy to be dealt with and this happens also through the way it is delivered to them.

We all know that there are lots of information that should be delivered to the kids at a specific age so they could understand the world they are living in. We have other videos related to the body of the human being, such as the heart (https://www.youtube.com/watch?v=SA7XEp_97FQ) and the bones (https://www.youtube.com/watch?v=KWnvP97FdX0) which will let the kid know more about his/her body, and there are also those educational videos related to the weather such as those about tornadoes (https://www.youtube.com/watch?v=OWA9dpLtNrU), hurricanes (https://www.youtube.com/watch?v=ye0wWBOKIZY), tsunamis (https://www.youtube.com/watch?v=q1mozwcqKBE) as well as thunder and lightning (https://www.youtube.com/watch?v=6i8hYEkiqSE) which will also explain to the kids the things they should get to know about the scientific phenomena that might happen around them.
